Check out the Next Generation House by Sou Fujimoto Architects. It's like a house built with Jenga blocks but it's actually a small housing module for weekend use located on the edge of a forest overlooking the River Kuma at Kumakura, Japan. The small pavilion, a 4×4 meters cube, is made by assembling solid japanese cedar blocks kept in place by their own weight and connecting metal cables running through vertical drill holes.
